Hi all,

For the app I'm writing, it will have 3 elements in the XML document it reads. The first 2 will only have one child element. The third one will be from 1 to whatever.

I'm also designing the app that will create the XML file for the app to read also, so a couple of questions:

Would it be easiest to introduce a fourth element to the XML that says how many children the 3rd element has? Or is there an easy way already to get this and just run a for next loop to read each child?

Thanks in advance!

Chris

Maybe sth. like this would do:

<counted_element count=3>
<child>1>/child>
<child>2>/child>
<child>3>/child>
</counted_element>

or similar. Besides making the count an attribute of the root node of counted elements you could simply use a standard pascal loop:

n: XMLNode;

{ this is only pseude code ... }
while (xmldoc.hasMoreChilds()) do begin

	n := getChild();
	... process n ...

end:

For real code http://wiki.freepascal.org/XML_Tutorial mwill help.

Hi Marc,

Thanks for the feedback. One more question and I think I'm done for now and able to finish the program I'm writing:

If FindNode does not locate a node with the given name, what does it return?

Thanks,

Chris

I don't know. It looks like it would be the first child of the subnode you're working at. I'm not sure if that first child can be a nil pointer, so you need to check yourself or someone else has to answer this question.

But it is easy to jump to the implementation of FindNode() yourself:

1. Put the cursor on the function call to <yourxmldoc>.FindNode()
2. klick the right mouse key
3. in the popped up menu select "Find Declaration of FindNode"
4. hit the keys Shift+down (arrow)

After Step 3 you're shown the class declaration, then after the fourth step the cursor is sitting in the implementation of the method in question. Then you can read the code.

Have fun,
Marc
